摘要：

我国主要烟叶类型烟草特有亚硝胺(ＴＳＮＡ)水平排序为:白肋烟＞沙姆逊香料烟＞烤烟＞巴斯马香料烟,其平均含量分别为１０．２５、０．８９、０．２５和０．０３μｇ/ｇ。在白肋烟和香料烟中,ＮＮＮ和ＮＡＴ为主要的ＴＳＮＡ,约占总ＴＳＮＡ的９６%,且在总ＴＳＮＡ含量较高的烟样中,ＮＮＮ占有较大比例。在烤烟中,ＮＮＮ、ＮＡＴ和ＮＮＫ含量水平相差较小,且以ＮＡＴ含量相对较高。我国烤烟型、混合型、雪茄型卷烟和雪茄的总ＴＳＮＡ含量平均分别为０．２１１、３．３０２、３．３９和１２．６６μｇ/ｇ。与国外样品相比,我国烤烟烟叶、烤烟型卷烟和混合型卷烟ＴＳＮＡ含量均显著低于国外水平。相关分析表明,烟叶和卷烟中的ＴＳＮＡ含量与降烟碱水平呈显著正相关,其中ＮＮＮ与降烟碱相关性最大,相关系数达０．８６３３。
